1. First, the basic concept of CNC

CNC is the abbreviation of computer numerical control, which is a technology that controls the movement and processing of machine tools through computers. CNC technology inputs digital instructions into the machine tool controller to control the machine tool to perform various complex motion and processing operations. The application range of XuFeng CNC technology is very wide, including machining, 3D printing, laser processing, electronic components processing and many other fields.

2. Second, the basic principle of CNC technology

The basic principle of CNC technology is to input digital instructions into the machine tool controller to control the machine tool for motion and processing operations. The control system of CNC machine tool is mainly composed of the following parts:

（1）Numerical control system: The numerical control system is the core part of the CNC machine tool, which is responsible for receiving and processing the digital instructions input by the user, and converting them into machine tool control signals. The numerical control system is usually composed of a computer, a control card, a servo motor, etc., and can realize high-precision, high-efficiency, and high-stability machine tool movement and processing operations.

（2）Machine tool structure: The machine tool structure is the physical part of the CNC machine tool, including the machine bed, worktable, spindle, etc. The structure of CNC machine tools is usually more complex than that of traditional machine tools, and it can realize more diverse motion and processing operations.

（3）Sensor: The sensor is an important part of the CNC machine tool. It can monitor and feedback the movement and processing process of the machine tool to realize automatic control. Sensors generally include position sensors, force sensors, temperature sensors, and the like.

The working principle of CNC machine tools is: the user inputs digital instructions, the numerical control system receives and processes the instructions, converts them into machine tool control signals, controls the machine tool to perform various movements and processing operations, and at the same time, the sensor monitors the movement and processing process of the machine tool to realize automatic control .
